Adaptive Prompt Cycle for Brain Disorder Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brain disorder evaluation apparatuses fail to adjust the prompt cycle of body movement tasks according to individual differences, leading to misjudgment of bradykinesia in older individuals and fatigue during testing, as they rely on preset intervals that do not account for subject-specific variations.
Innovation Solution
A brain disorder evaluation apparatus that includes a data processing unit capable of adjusting the prompt cycle based on body movement accuracy, using a body movement task selection part, data obtainment part, indicative data generation part, body movement accuracy computation part, and cognitive impairment degree evaluation part to generate an indication cycle tailored to each subject's performance level, incorporating input information such as age and health condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a preset prompt interval time is used for all subjects, then the evaluation process is simple and standardized, but it causes misjudgment of bradykinesia in older individuals and fatigue during testing due to individual differences
Solution Approach 1:
The patent applies dynamics by making the prompt interval time adjustable rather than fixed. The system dynamically adapts the prompt cycle based on individual subject characteristics (age, health condition) and real-time body movement accuracy feedback. This resolves the contradiction by allowing the evaluation system to remain simple for standard cases while automatically adjusting for individual differences, thereby maintaining evaluation accuracy without requiring complex manual configuration.
Solution Approach 2:
The patent changes the parameter of prompt interval time from a constant preset value to a variable that can be adjusted based on subject parameters (age, health condition) and performance metrics (body movement accuracy). This parameter change enables the system to accommodate individual differences and prevent both misjudgment of bradykinesia and subject fatigue, resolving the reliability-complexity contradiction.
2Productivity
If the prompt interval time is shortened to increase testing efficiency, then productivity improves, but subjects with simple bradykinesia may be misdiagnosed as having dementia
Solution Approach 1:
The patent implements feedback by using body movement accuracy data to adjust the prompt interval time dynamically. The system monitors subject performance in real-time and adjusts the timing of subsequent prompts based on measured accuracy. This feedback mechanism ensures that testing efficiency is maintained through optimized intervals while preventing misdiagnosis by adapting to each subject's actual motor response capabilities.
Solution Approach 2:
The system dynamically adjusts the prompt interval based on individual subject characteristics and real-time performance. For subjects with slower motor responses (bradykinesia), the system automatically extends intervals to prevent misdiagnosis, while for subjects with normal response times, it maintains shorter intervals to preserve testing efficiency. This dynamic adaptation resolves the contradiction between productivity and measurement precision.
3Measurement precision
If the prompt interval time is extended to accommodate slower responders, then diagnosis accuracy improves, but subjects feel tired and testing cannot continue
Solution Approach 1:
The system dynamically adjusts prompt intervals based on individual subject characteristics and real-time performance metrics. Rather than using a uniformly extended interval that would cause fatigue, the system optimizes intervals for each subject's actual capabilities, extending them only when necessary for accuracy while maintaining shorter intervals when appropriate to prevent fatigue and enable continuous testing.
Solution Approach 2:
The patent changes the prompt interval parameter from a fixed extended value to a variable that adapts based on subject parameters (age, health condition) and performance (body movement accuracy). This allows the system to achieve diagnosis accuracy by extending intervals only when necessary while avoiding excessive extension that would cause fatigue, thus resolving the contradiction between measurement precision and loss of time.
4Reliability
If individualized prompt cycles are implemented for each subject, then evaluation accuracy improves, but the system complexity increases due to additional data processing requirements
Solution Approach 1:
The patent applies universality by designing a data processing system that handles multiple functions within a unified framework: storing subject parameters (age, health condition), computing body movement accuracy, determining appropriate prompt intervals, and adjusting timing in real-time. This multi-functional integration achieves individualized evaluation accuracy while avoiding the need for separate complex systems for each function, thus resolving the reliability-complexity contradiction.
